Ceromasiops, nov. gen. 



Proposed for Ceromasia rufipes B. B. in the sense of Pan- 

 tel (1910). Deposits small black microtype eggs, presumably 

 on plants but almost certainly on food of host. Has presum- 

 ably an elongate uterns. Forms have been recorded under 

 this specific name as reared from Forficulidse. 



Myxexoristops, nov. gen. 



Proposed for Myxexorista pexops B. B. in the sense of 

 Pantel (1910). Deposits large slate-gray microtype eggs, 

 presumably on plants. Has a shortened uterus and a less 

 number of ovarioles than the forms with more elongated 

 uterus. 



Eumusca, nov. gen. 



Proposed for Musca corvina Fab. in the sense of Portch- 

 inski (1885) for his egg-depositing form, whose enlarged eggs 

 are provided with an elongated curved appendage and depos- 

 ited evidently after having been incubated in the uterus. 



Eudasyphora, nov. gen. 



Proposed for Dasyphora lasiophthahna in the sense of 

 Portchinski (1885). Deposits eggs. 



HOW EMPHOR DRINKS. 



On August 19 I was collecting insects in the marshes of the 

 Eastern Branch, on the outskirts of Washington. At the 

 edge of the marsh some large holes had been dug", apparently 

 to furnish drinking-water for cattle. On approaching one of 

 these water-holes I found large bees rapidly descending di- 

 rectly to the wa.ter-surface and others rising from it. The 

 bees alighted unhesitatingly upon the water and rested upon 

 the water-surface with legs spread wide and the wings folded 

 upon the back In this position the bees usually remained 

 about ten seconds; the proboscis was in contact with the water 

 and they were evidently drinking. New individuals were 

 constantly arriving and sometimes four or five bees rested 

 upon the water-surface at one time. All the visitors appeared 

 to belong to one species, which Mr. Crawford has kindly de- 

 termined as Emphor bombiformis Cresson.
